CarbonClean: A Thermal Battery for More Efficient Energy Management


05.11.2026

Industrial production in modern environments faces challenges related to energy efficiency and reducing environmental impact. One of the most common issues in production processes is the loss of thermal energy, which remains unused and represents a direct cost for companies.

With the aim of addressing this issue, the company StarBeta from Kragujevac has developed an innovative thermal battery, CarbonClean, designed for storing and reusing excess heat. The development of this solution was supported through the Innovation Fund’s program, financed by the European Union, enabling further technical advancement and preparation for deployment in real production environments.

CarbonClean enables the collection, storage, and reuse of heat at the moment it is needed, with the ability to charge and discharge simultaneously. Continuous operation has been achieved through the development of multiple independent reservoirs, each of which can be managed independently. This represents a key technical solution that ensures stable and continuous system performance.

“Our starting point in developing the project was the desire to improve energy management while reducing carbon dioxide emissions in industry. We achieved these goals by creating a single device, the CarbonClean thermal battery, which collects, stores, and reuses thermal energy when it is needed,” said Gordana Vuksanović from the StarBeta team.

The application of this solution enables significant reductions in energy costs, particularly in industries with high levels of heat loss, such as pharmaceutical, food processing, and other process industries. The solution is applicable in all systems where excess heat is generated during production processes. At the same time, it reduces the need for additional energy sources, directly improving production efficiency and lowering emissions.

“Once installed in a selected facility, CarbonClean contributes to more efficient use of thermal energy, and consequently electrical energy. In large production systems, heat losses often go unnoticed, but over time they significantly impact overall costs and energy efficiency,” Vuksanović explained.

“The support of the Innovation Fund was important not only as financial assistance, but also as additional credibility for the development of the project,” she added.

The project is currently in its final phase of testing in real production environments, after which market entry is planned. The company expects adoption both in the domestic and international markets.

The development of the CarbonClean solution is based on a clear need to use energy more efficiently and responsibly. In conditions of rising costs and increasingly stringent environmental standards, solutions like this represent a practical step toward more efficient and sustainable industrial production.
